MACHINE FOR BENDING TIRES.

Specification of Letters Patent No. 27,143, dated February 14, 1860.

To all whom t may concern:

Be it known that we, WILLIAM Mesi-Inn, IsAAc H. MosHER, and JOHN J.HARRIS, all of the town of Green, in the count-y of Chenango, State ofNew York, have invented new and useful Improvements in Forms andFixtures for Bending Tires for )Wheels to Vehicles and Hoops and Bandsfor Tubs and Casks; and the following is a clear and exact descriptionof the same, reference being had to the accompanying drawings, making apart of this specification.

The nature of our invention consists in the simplified arrangement bywhich we use a wedge, or tapering key, to control the length of thelever that holds a roller to press upon the bar to adjust it to thethickness, and the scroll shaped former to hold the bar, so that theroller will pass over the bars, and complete the bending at oneoperation.

To enable others skilled in the art, to make and use our invention wewill describe it referring to the drawings, and the letters thereon.

Figure l, represents a top view of the former (A,) made of wood ormetal, which is nearly a circle, except on the side in which the end ofthe bar (2),) to be bent is inserted, which is brought in from a truecircle toward the center like a scroll. There is an opening (61,) toreceive the end of the bar (6,) which is to be bent. On starting thebend comes within the circle the thickness of the tire so as to allowthe circle to be completed by passing once around the lever (E,) onwhich is placed a friction roller (1),) in a line of the face, or uppersurface of the former (A,) which is to be firmly secured from turningaround in a fixed position by a timber (E,) bolted to the under side, asseen in (Fig. 2,) which shows the edge view of the former (A,) roller(1),)

and lever (E,) supporting bracket (e) all combined.

In the center of the former (A,) is a strong bolt (0,) and nut, on whichthe lever (E,) hangs, it having a mortise or elongated hole for the bolt(0,) and transversely is a mortise into which is fitted a tapering key,or wedge (0,) to bear against the side of the bolt and thereby lengthenor shorten the distance of the friction roller (D,) from the center, bythe position the wedge is placed in, the roller is accommodated to thethickness of the bar, so as always to press it firmly against theperiphery of the former and when the roller has set the tires the entirecircle, the wedge, or key, can be started back at one blow with a hammerso as to pass over and liberate the hoop, or alow the bending to becontinued over the IVe have found by practical experience that the abovedescribed former and fixtures, is a more perfect and expeditious mode ofshaping tire for wheels, or bands, or hoops of any kind, size ordimensions, than has ever before come to our knowledge.

And having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is*

The scroll shaped stationary former the mode of holding the end of thebar to be bent, 'the manner of adjusting the friction roller, by thewedged shaped key through the lever, bearing against the center belt,all in combination as specified, and for the purposes set forth.
